SEALED RECEITACLE.

Specicatiqn ot Letters Patent.

Patented July 15, 1919.

To all whom 'it may concern.' y

Be it known that I, ANDREW S. Nico, a citizen of the United States, residin i at Le Roy, in the county of' Genesee and Stateof New York, have invented new and useful Improvements in Sealed Receptacles, of which the following is a specification.

My present invention relates to improvements in sealed receptacles of the type adapted to provide a moisture-proof inclosure for powdery or other material, and the object of the invention is to provide an improved seal for the receptacle which comprises a cli of metal or other rigid material which is fo ded over the edges of the mouth of the receptacle and is corrugated, indented, or otherwise shaped after its application to i the mouth of the receptacle so as to not only lirmly secure or retain the clip upon the receptacle but to also produce corresponding corrugations or indentations in the lapped ed es of the rece tacle, which cor ugations or indentations wi l erfect an eflicie t moisture-tight seal whic will not onl revent entrance of moisture to the receptac ey ut will also efectually retain the contents* within the receptacle.

To these and other ends, the invention consists in certain improvements, and com-` binations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claim at the end of the specification.

In the accompanying drawing Figure 1 is a perspective view showing n seal constructed in accordance with one embodiment of the present invention.

Fig. 2 represents a section taken longitudinally of the seal and on the line 2-2 of section taken trans-l Fig. 3 represents a on the line 3-3 of Vesely, through the seal Fig. 4 is a perspective view of the upper l portion of a receptacle provided with a seal constructed in accordance with another embodiment of the invention.

Fig. 5 represents a longitudinal section of the seal taken on the line 5--5 of Fig. 4, and Fig. 6 represents a transverse section of the seal on the line 6 6 of Fig. 4.

Similar parts are designated by the same reference characters in the several views.

The present invention is applicable generally to receptacles of various kinds adapted for use where it is desirable or necessary to provide a closure which will confine the contents'wthin the receptacle and which will effectually seal the contents from moisture or atmospheric inuences. The invention is paryticularly applicable to a receptacle of the type shown in Letters Patent, No. 1,101,430, granted June 23, 1914, to Otis E. Glidden and myself. The seal forming the subject matter of `'the Apresent invention is shown applied to a rece tacle of the type shown and described fu ly in that patent. It is to be understood, however, that the invention is notrestricted in its use to receptacles of the specific type referred to, and also that the invention is not restricted to the precise constructions of seals shown herein, as equivalent seals are contemplated and will be included within the scope of the claim.

In the present instance the receptacle is in the form of the so-called Satchel bottom bag. This bag` is made up preferabl in the manner described in the atent hereinbefore referred to, it being su cient for the present purposes to say that it is made from a sheet of paper or other suitable material which is folded to form the bottom or the space for the contents, and the margins of the sheet are all brought together so as to extend in a line across the top of the bag, thus forming the mouth thereof. Materials of dili'erent kinds may be used in makin the receptacle. It is generally refer*- ab e, however, to employ a material w iich is impervious to moisture such, for exam le, as paper coated or treated with para or wax. To avoid difficulties in the manufacture of receptacles of 'this kind by machinery, it is preferable to employ a paper which is coated with araliin or wax on one side and to so form Sie receptacle that the wax-coated side thereof will be at the inner side of the receptacle.

The seal, according to the present invention, is applied to and made upon the bag after the contents have heen introduced into the bag' 0r receptacle. The margins of the paper or material composing the receptacle and which extend in a line across the mouth of the receptacle are bent laterally. after the contents have been introduced into the bag, these laterally bent margins of the paper forming a laterally directed portion 1 which 1s composed of the lapped margins ioo - shown in Figs. 1-3 inclusive surrounding the mouth of the receptacle. Preferably this laterally directed ortion 1 is subjected to compression and t e corner 2 which joins this laterally bent portion to the body of the bag is also bent sharply and subjected to compression to form a sealing corner.

The sealing device in the embodiment comprises a cli 3 of rigid or substantially rigid matcria sheet metal being general y preferable. As shown, this sealing device is formed by doublin a strip or sheet of metal or other materia to form an intermediate bend 4 and upper and lower wings 5 and 6. The.

sealing device is applied to the laterally di'- rected portion 1 of the bag during the course of the bag or receptacle through the machine, the clip or sealing device being preferabl of a length corresponding to the lengtli of the laterally directed portion 1 of the bag, and it is so applied thereto that the upper and lower Wings 5 and 6 of the sealing device will engage the upper and lower sides of the laterally directed portion l, the intermediate or doubled portion tlof the sealin device abuttin against the free edge of t e portion 1. hile the clip or sealing device is in this position it is sub- `ected to the action of corrugated compressing jaws which operate upon the Wingle 5 and 6, forming corrugations 7 in t ese wings, and by the same operation compressing and forming corresponding corrugations in the layers of material composing the laterally directed portion 1 of the bag. TheseV corrugations preferably extend in a direction transverseliy of the length of the clip or the portion of the receptacle andI they serve not only to rigidly maintain the win s 5 and 6 of the clip under compression against the up er and lower sides of the laterally directe portion 1 of the receptacle, but these corrugations also positively maintain the corrugations in the layers of paper or material composing the laterally bent portion 1. Where, as 'in the present instance, these lapped layers of paper or material are coated with wax, the corrugations in such layers, in conjunction with the maintenace of pressure upon these layers, produce an intimate contact between the layers of paper, for the reason that the wax coating on these la ers of paper is caused by the compression o the corrugations to produce an exact conformity between the lapped layers of paper which will completely close the mouth of the bag to exclude moisture and to retain the contents in the bag. The

rigidity of the clip maintains the seal effectually.

In the embodiment of the invention shown in Fig. 46 inclusive, a clip 8 of metal or other rigid material is applied to the laterally directed portion 1 of the bag, as in the preceding instance, but in this case the clip and also the lap ed layers of paper comosin the latera y bent portion 1 are sub jecte to a compression between jaws having crossed serrations thereon, producing corres onding crossed serrations 9 on the upper an lower wings 10 and 11 of the clip, and by the same operation the la ers of paper or` material composing the laterally bent portion 1 are correspondingly compressed and formed with these crossed serrations. In this instance also the crossed serratioiis on the upper and lower wings of the clip not only stillen these wings, but they also maintain sharply the serrations in the layers of paper forming the laterally directed portion 1 of the bag and where, as in the present instance, these la ped layers of paper are coated with para n or wax, the formation of these serraticns causes intimate correspondence between the lapped layers of paper, excludin moisture and retaining the contents within the receptacle.

In bothr embodiments shown, the free edges of the wings of the clip terminate in immediate proximity to the sealing corner 2. The clips therefore serve to maintain the layers of wax-coated paper in intimate contact at this sealing corner, and the clips also prevent relative displacement of the layers of paper, to the end that the seal is ellectually maintained.

I claim as my invention A paper receptacle havin at the mouth thereof lappe and bent laterally at a sharp an le to form a sealing corner, and a clip o rigid material iitted over the free edge of the la ped laterally bent portions of the material), said lapped portions of the material and the clip having corresponding the corrugations in the clip serving to the corrugations in t e lapped portions of the aper receptacle to prevent relative sli ping of the plies of said lapped portions.

n testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
